As a guide, I hang my derriere over a cliff edge every day, often for hours at a time. I’m constantly securing myself into anchors while belaying, instructing and overseeing clients. In these cases, I like being snug on the anchor with my weight on the rope or other connection–it chases away the little butterflies in my stomach. Thus, having a quick and efficient way to protect myself while also providing adjustability is invaluable.
Sometimes seen as an aid-specific tool for the pin scars on big-wall routes in Zion and Yosemite, offset cams can be invaluable almost anywhere.
